WATCHMANS TIME-RECORDER.

SPECIFICATION forming part of Letters Patent No. 426,438, dated April 29, 1890.

Application filed November 23, 1889. Serial No. 331,399. (No model.)

To all whom it may concern: forms, as shown, a seat for the rear side of Be it known that we, CHARLES E. EGAN an ordinary hollow rubber ball Z), which is and HENRY F.

Supcase, which is preferably formed of metal, has ported centrally upon the outer portion of the its rear open end secured to a similar basehand-post h is a thin paper disk 2', which is block a. The inner face of this base-block a clamped between a cap 70, screwed upon the is provided with a concave depression, which outer endof the hand-post, and a washer la, 10o

surrounding said hand post and abutting against a collar 73', formed thereon. This paper disk or dialzhas its face divided by twelve (12) printed lines. Each space between two of said lines represents the distance which said dial will be forced to travel, owing to its connection with the hand-post, during one hours time. If desired, the spaces between said hour-lines may be so printed or lined as to represent the desired fractions of an hour. The hour represented by each line is indicated by a printed figure upon the dial opposite said line. Secured to the frame-plate g at a point beneath the clock-work mechanism is the rear end of a guide-arm m. This arm extends outwardly to a point vertically beneath the lower edge and center of the dial i, at which point it is bent upwardly, said upwardly-bent portion being divided to form two upwardlyextending parallel arms on,

which loosely embrace the lower portion of the dial 2'. Extending upwardly from the horizontal portion of the arm m, near the center of the length thereof, is an arm 'n, which terminates at a point horizontally opposite the vertically-divided portion of the arm m. Supported by the upper portion of said arm 'n and passing therethrough is a short horizontal tube 19, the rear end of which extends into a hole formed in the frame-plate g and communicates, as shown, with the remaining end of the tube 6. The forward end of the tube 19 is connected with the rear side of and made to communicate with the interior of a flattened disk-shaped air-chamber q, the faces or diaphragms of which are preferably formed of thin metal. Secured to the center of the front face of this air-chamber is the rear end of a needle 7", the forward end of which extends within a transverse needle-h ole g, which passes through the guide-arms m. Said forward end of the needle r is pointed and normally terminates in the rear of the dial 1'. Surrounding said needle and having its ends bearing between the rear face of the rear arm m and the front face of the air-chamber q is a coiled spring 3.

2f represents the key, by means of which the bulb b is compressed, as herein after described. This key consists, as shown, of a head 25' and a cylindrical stem, the greater part of which is divided by a vertical slit to form two par allel prongs of such form as to admit of their insertion through the opening 0 of the keyway.

The operation of my device is as follows: The herein-described recording-station mechanism (shown in Figs. 6, 7, and 8 of the drawings) may be located at the office of the factory or other building where itis to be used, or at any other convenient point which is not accessible to the watchman, and said mechanism may, if desired, be provided with a suitable case having a lock. The sendingstation (shown in Figs. 1,2,and 3 of the drawings) may be located at the point in the building to be visited by the watchman. The dial is so set that the line which represents the time corresponding with the actual time of the day is immediately opposite the needlehole of the guide-arm m, and the clock-work mechanism in rear is so adjusted as to cause said dial to make a complete revolution every twelve hours. The watchman visiting the sending-station inserts the key 25 into the keyhole of the neck a, the prongs t of the said key entering the openings 0 and coming in contact with the button d on opposite sides of the tongue (1'. He then presses upon said key, which pressure, through the consequent inward movement of the button (I, will operate to compress the ball or bulb b, as shown in dotted lines of Fig. 2 of the drawings. The compression of said ball will result in forcing the air contained therein out through the tubes 6 and 19 into the air-chamber g at the recording-station. Owing to the faces of the latter being of thin material, the increased volume of air thus forced therein will cause an expansion or outward movement of the air-chamber face, which, through its connection with the needle 0', will operate to draw the latter sufficiently forward to cause its point to penetrate the paper disk or dial. The key being withdrawn from the sendingbox, the bulb or ball will be allowed to return to its normal position, the air forced therefrom returning to fill the same. The return of the air, together with the tension of the spring s,wh1ch is necessarily slightly compressed when the face of the air-chamber is expanded, will cause the said air-chamber to resume its usual form, and will draw the needle from the dial.

By the herein-described construction it will be seen that the needle-hole formed, as above described, in the dial will be in line with the figure or mark on said dial representing the hour of the day, thus indicating to an ob-' server the hours at which the watchman visited said station.

The herein-described recording device, although simple of construction, is at once accurate and reliable and can be manufactured at a comparatively low cost.

Having now fully described our invention, what we claim, and desire to secure by Letters Patent, is
